- GEATE' ATTACHMENT FOR STOVES AND FURNACES.

Application filed October 5, 1921. Serial No. 505,504.

To all u; 7mm it may concern.

Be it known that I, RAY O. DURsr, a citizen of the United States, residing at Bradford, in the county of Miami and {State of Ohio, have invented certain new and useful Improvements in Grate Attachments for Stoves and. Furnaces, of which the following is a specification.

The present invention consists of a grate attachment for stoves and furnaces.

It is well known in the art to provide an: tight stoves which are especially adapted for use in railway cabin cars, etc., where the stove is, of necessity, subjected to constant vibration, periodical air blasts etc., thereby minimizing possibility of the hot coals, ashes etcfbeing projected from the stove to the floor. However, in these types of stoves now in use it is necessary to open the ash door in order to shake the grate with the result that sparks are emitted from the grate as is also coal gas dust, etc, which prove very offensive, if not inyurlous, to the attendant. It is the principal object of this invention therefore, to provide a grate and associate mechanism which will permit the grate to be shaken without the necessity of opening the ash door or otherwise venting the stove.

Another object of the invention is to provide means for locking the grate from move ment thereby preventing accidental shaking of the grate by the swinging movement of a railway car or other vehicle in which it is carried.

The above and other objects of this invention will be in part described and in part understood from the following description of the present preferred embodiment of the invention taken in connection with the accompanying drawings wherein Fig. 1 is a fragmentary front elevational View partly in section of a stove embodying my improvement.

Fig. 2 is a horizontal sectional view of the stove base showing a grate constructed in accordance with this invention and the shaker means attached thereto, the said shaker attachment being shown in a closed position.

Fig. 3 is a similar view showing the shaker attachment in an open position; and

Fig. 4 is a detail fragmentary elevational view of the stovebase showing to advantage the shaker locking mechanism.

In the drawings a portion of an air-tight or ho-t blast stove 5 is shown the body and base of which may be of standard construc tion. The base 6 of the stove is equipped with an ashdoor 7 covering an opening through which the ash pan may be removed in the usual way.

In this type of stove, a rotary grate such as that shown at 8 in Fig. 2 is provided. When constructed in accordance with this invention the grate has an arm 9 extended from its periphery and terminating short of the ash door 7. The outer end of said arm is provided with an elongated slot 10 which receives one end of a shaker rod 11. he opposite end of the rod extends through an opening in one side of the stove base 6 andhas a handle 12 formed on its extremity. As is apparent reciprocation of the rod 11 will cause the grate to be rotated in an obvious manner and for an obvious purpose. By providing the elongated slot 10 ample play of the rod 11 will be permitted so as to insure free movement of the grate without possibility of binding.

In order to prevent accidental movement of the grate suitable locking means is provided. formed on the rod 11 in proximity to the handle 12. The collar is adapted to rest in a complemental recess 14 formed in the side of the base 6. A locking tumbler 15 is pivotally mounted upon the base 6 in proximity to the recess 14C. Normally, the tumbler will gravitate into engagement l'JQJWGBIl the handle 12 and collar 13 thereby preventing movement of the rod 11.

In use of this device when it is desired to shake the grate the tumbler 15 is elevated so as to permit withdrawal of the collar 18 from the recess 14. After this has beendone the tumbler may be permitted to gravitate into engagement with the rod 11 and the latter reciprocated by the handle 12, in an apparent manner. The grate is relocked by simply urgingthe handle 12 inwardly and disengaging the tumbler 15 until the 'collar 13 seats in the recess 14 following which the tumbler is permitted to gravitate into reengagement between the handle 12 and collar 13.

The above described device will eliminate the necessity of opening the ash door or in any way venting the stove when the grate is to be shaken at the same time permitting the grate to be thoroughly agitated in the usual way. The device is simple and This means consists of a collar 13 may be applied to standard types of stoves engaged with said grate arm, a collar formed ithout appreciable cost. Various changes may be made in this sion of the stove body, a locking plate deviceespecially in the details of censtrucmounted on the stove body and movable tion, proportion and arrangement of parts across the depression of the latter to pre- Within the scope of the appended claim. vent disengagement of the collar therefrom.
